The elevation chart looks like a heart patient’s ECG. More than 200 km of the journey is above 4,000 m, with no permanent human habitation. The enemies are bitterly cold, cutting headwinds, broken roads, heartbreaking uphill climbs and, more than anything else, extreme gains in altitude. When you finally get to Leh, you will have the right to try cycling up to Khardung La, one of the highest motorable roads in the world.
